Smatch is a C static analysis tool, but with a lot of kernel specific checks. The big thing in this release is that the type information has now been pushed to the lowest levels. It broke a bunch of stuff including to compiles on older versions of GCC but Emil Tantilov fixed that (thanks!). It should be Ok now. Other changes are that the cross function tracking has been improved (this requires the database). There is a new check for sprintf() overflows. The way to use Smatch is: git clone git://repo.or.cz/smatch.git cd smatch make cd ~/path/to/kernel [ This next step is optional if you want to build the database. If you build it several times the database becomes more complete. ] ~/path/to/smatch/smatch_scripts/build_kernel_data.sh ~/path/to/smatch/smatch_scripts/test_kernel.sh It creates warns.txt file with all the warnings. Or alternatively if you just want to check one file then the command is: ~/progs/smatch/devel/smatch_scripts/kchecker drivers/file.c regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe smatch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
